Official title
A Prospective, Single-Arm, Open-Label Pilot Clinical Study to Evaluate Efficacy and Safety of Topical 10% 35 kDa Hyaluronan (HA35) Gel for Post-Dental Gingival Pain and Swelling
Overview
This is a prospective, single-arm, open-label, pilot clinical study to evaluate the efficacy and safety of 10% high-concentration 35 kDa hyaluronan (HA35) gel delivered via gel-soaked cotton balls in patients with gingival pain and swelling after dental procedures. Eligible participants will gently chew and retain the gel-soaked cotton balls on the affected area for 30 minutes. The primary objectives are to assess changes in gingival pain and swelling at 1, 30, and 60 minutes after application. Safety and local oral tolerability will be evaluated throughout the observation period. This is a minimal-risk, non-pharmacological, non-invasive intervention.
Detailed description
This prospective, single-center, single-arm, open-label pilot clinical study investigates the analgesic and anti-inflammatory efficacy of 10% high-concentration 35 kDa hyaluronan (HA35) gel delivered via gel-soaked cotton balls for managing gingival pain and swelling following dental procedures (including restoration, transplantation, extraction, and scaling).
Eligible subjects will place HA35 gel-soaked sterile cotton balls on the affected gingival area, gently chew and retain the cotton balls in place for 30 minutes to allow sustained local infiltration. Pain intensity will be assessed using a 0-10 Numeric Rating Scale (NRS), and gingival swelling using a 0-10 Visual Analog Scale (VAS) at baseline, 1 minute, 30 minutes, and 60 minutes after application.
Oral irritation, allergic reactions, and adverse events will be monitored for safety assessment.
This is a non-invasive, non-pharmacological oral topical intervention with minimal risk to participants. All procedures will be conducted in accordance with the Declaration of Helsinki, and written informed consent will be obtained from all subjects prior to enrollment.
Interventions
- Device 10% High-Concentration 35 kDa Hyaluronan (HA35) Oral Topical Gel
Topical oral gel containing 10% high-concentration 35 kDa hyaluronan fragment. Delivered via gel-soaked cotton balls that are gently chewed and retained in the mouth for sustained infiltration into the affected gingival area to relieve post-dental pain and reduce swelling.
Primary outcome measures
- Change in Gingival Pain NRS Score (0-10) [Time frame: Baseline to 1, 30, and 60 minutes after application]
Secondary outcome measures (3)
- Change in Gingival Swelling Severity (0-10 VAS Score) [Time frame: Baseline to 1, 30, and 60 minutes after application]
- Onset Time of Gingival Pain Relief [Time frame: Within 60 minutes after application]
- Incidence and Severity of Oral Adverse Events [Time frame: Throughout the 60-minute observation period]
